It’s a big college football weekend featuring four top 25 matchups. Check out the top five games to watch.

Buzz: Oklahoma State has been impressive on the road, with the Cowboys going 13-3 under quarterback Mason Rudolph. During that stretch, Rudolph has thrown for more than 5,000 yards, 32 touchdowns and 15 interceptions. Mountaineers quarterback Will Grier, meanwhile, leads the country in touchdowns passes (26) after throwing for close to 2,500 yards. This game starts a stretch of three consecutive matchups against ranked teams for Oklahoma State, with Oklahoma and Iowa State on deck.

No. 2 Penn State (7-0, 4-0 Big Ten) at No. 6 Ohio State (6-1, 4-0)

Saturday, 3:30 p.m. – FOX

Buzz: This build up for this game started last season after Penn State held on to defeat Ohio State 24-21 on Oct. 22, 2016. The win propelled the Nittany Lions to a Big Ten title, but not a spot in the semifinals of the College Football Playoff. The bid instead went to the Buckeyes. Penn State is looking for its first win in Columbus since 2011, while running back Saquon Barkley could cement his status as Heisman Trophy favorite with a stellar performance.

No. 14 NC State (6-1, 4-0 ACC) at No. 9 Notre Dame (6-1)

Saturday, 3:30 p.m. – NBC

Buzz: Notre Dame is 12-15 against teams ranked in the top 25 during coach Brian Kelly’s tenure, including a 1-3 record against ranked teams from the ACC. NC State hasn’t been ranked this high in more than a decade (2003), but what appeared to be quality wins over Florida State and Louisville early on don’t look nearly as good now. The Wolfpack have turned the ball over three times so far this season, including twice in a season-opening loss to South Carolina. Notre Dame, meanwhile, has forced 17 takeaways.

No. 4 TCU (7-0, 4-0 Big 12) at No. 25 Iowa State (5-2, 3-1)

Saturday, 3:30 p.m. – ABC/ESPN2

Buzz: Iowa State is off to its best start since 2002 and the Cyclones are ranked in the Associated Press top 25 for the first time since 2005. Much of the team’s success this season can be attributed to fielding the best scoring defense (15.2 points per game) in the Big 12. Iowa State has only allowed 17 total points in the second half of its four conference games this season. The team will be tested by TCU’s high-powered offense. Since 2000, the Horned Frogs are 26-2 when ranked in the AP top five.

No. 3 Georgia (7-0, 4-0) vs. Florida (3-3, 3-2)

Saturday, 3:30 p.m. – CBS

Buzz: Georgia comes into this rivalry showdown looking to remain perfect. The last time the Bulldogs entered the game undefeated and won was 1982. That was the year UGA went 11-0, but Penn State edged the Bulldogs for the national title. Florida, meanwhile, has upset an undefeated Georgia team twice -- in 2005 and 2002. The struggling Gators are looking for their second win over a top-three program since 2010.
